Javascript: Multiple checkboxes to be checked using javascript

Question

I am trying to get the second javascript line in this example to work (being able to select the check box from javascript): http://jsfiddle.net/eTvDB/

Essentially, if I don't use xxx[] form for the name, I won't be able to obtain an array in PHP. Any ideas?

Thanks.

Well elements["select2[]"].options[0] doesn't make sense when select2[] is the name of some checkboxes and not the name of a select element. If the idea is to check the first checkbox with that name document.forms["myForm"].elements["select2[]"][0].checked=true; works. If the idea is to check all of that name there are other ways to do it... — nnnnnn

Use:

document.myForm['select2[]'][0].checked = true;

Or

document.getElementsByName('select2[]')[0].checked = true;

The demo.
